如何通过代理使用卷曲？

Question

，但它返回了有关第12行中缺少t_varible的错误消息。

<?

$url = '$_POST[1]';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1)
curl_exec ($ch); 
$curl_info = curl_getinfo($ch);
curl_close($ch);
echo '<br />';
print_r($curl_info);
?>

波纹管来自Curl到代理返回无内容

<?

$proxy = "66.96.200.39:80";
$proxy = explode(':', $proxy);
$url = "$_POST[1]";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);

$exec = curl_exec($ch);

echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
?>

目前居住在pelican-cement.com上，但也不起作用。

update： 感谢您的所有帮助，我进行了上述更改。现在它只返回空白屏幕。

<?

$url = $_POST['1'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_exec ($ch); 
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;
?> 

here是一个工作版本，已删除错误。

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

我添加了

CURLOPT_PROXYUSERPWD

如果您的任何代理都需要用户名和密码。 我将

CURLOPT_RETURNTRANSFER

设置为1，以便将数据返回到

Answer 1

变量。

I删除了第二个额外的

curl_exec($ch);

，这将阻止返回的变量。
我将您的代理IP和端口合并为一个设置。

I还删除了

CURLOPT_HTTPPROXYTUNNEL

和

CURLOPT_CUSTOMREQUEST

默认值。

如果您不想返回标题，请发表评论

CURLOPT_HEADER

。

禁用代理只需将其设置为null。

curl_setopt($ch, CURLOPT_PROXY, null);

任何问题都可以问，我每天都在与

cURL

一起工作。

我解释了使用卷曲代理所需的各种卷曲选项的使用。

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

root@applicatioserver：/var/www/html＃php connectiontest.php 61E23468-949E-4103-8E08-9DB09249E8S1 OPENSSL SSL_CONNECT：SSL_ERROR_SYSCALL连接到10.172.123.1:80

post在PHP脚本文件问题中声明代理设置已解决。

$ proxy = '10 .172.123.1：80'; curl_setopt（$ csession，curlopt_proxy，$ proxy）; //端口的代理详细信息

Missing semicolon so code is here..
<?
$url = '$_POST[1]';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1); **semicolon**
curl_exec ($ch); 
$curl_info = curl_getinfo($ch);
curl_close($ch);
print_r($curl_info);
?>

Answer 2

这里是一个经过良好测试的功能，我将其用于项目，并带有详细的自我解释评论

有很多次，当80以外的端口被服务器防火墙阻止，因此代码似乎在Local主机上工作正常，但在服务器上不正常。

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}
